Title: Improvements in or relating to radio communication systems
Inventor: COCKERELL CHRISTOPHER SYDNEY
IPC: H04J3/00
Filed: 1950-03-20
Abstract: 684,500. Transmission systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 31, 1951 [March 20, 1950], No. 6922/50. Class 40 (iv). [Also in Group XL (c)] The amplitude of a signal wave is periodically sampled, the samples being fed sequentially through a plurality of low-pass filters to modulate individually an equal number of closelyspaced carriers. In the embodiment described, there are one hundred carriers each associated with a low-pass filter, samples 1, 101, 201, &c., being fed to the first, samples 2, 102, 202, &c., being fed to the second and so on. The signal sampling rotary distributer SW, Fig. 2, is a motor-driven switch, the arm A1 of which traverses contacts U1 ... U100 to which the signal waveform WF is applied. The other arm A2 distributes the sample amplitudes to low-pass filters F1 ... F100 whose outputs modulate carriers spaced a minimum of 60 c/s. apart. The sampling frequency is 6 kc/s. so that each filter receives 60 samples per second, the filter pass-band being 30 c/s. so that the output is a wave S1 ... S100 whose amplitude is proportional to that of the original wave at intervals of <SP>1</SP>/ 60  of a second. A synchronizing signal comprises a 30 c/s. sine wave modulating an additional carrier. The I.F. output from the receiver R, FC, 1F, Fig. 4, is connected to filters CF1 ... CF100 to separate the individual carriers which are demodulated in circuits D1 ... D100. The demodulator outputs which reproduce the signal samples, are connected to the contacts K1 ... K100 of a distributer RA, which feeds them in succession through the lowpass filter LPF to reconstitute the signal wave. The motor M, driving the distributer, is synchronized by separating the synchronizing carrier in filter SF and passing the 30 c/s. modulation, derived in circuit SD, to a phase-splitter PS supplying the motor driving currents. In a preferred embodiment, the output from each low-pass filter at the transmitter is converted into a single side-band signal with suppressed or reduced carrier, the carrier frequencies differing by 40 c/s. The synchronizing carrier is modulated in addition by a 40 c/s. tone. At the receiver, harmonics of the 40 c/s. tone are derived to provide the suppressed carriers for demodulation.

Abstract: 609,124. Railway sleeping cars. BUDD MANUFACTURING CO., E. G. March 6, 1946, No. 6977. Convention date, March 17, 1945. [Class 103 (iv)] A sleeping berth has thin transverse walls 12, Fig. 3, separating adjoining rooms, and a fixed length bed 37 hinged at 38 is foldable against one of the walls and is capable of extending horizontally from wall to wall, whereby the overall length of a series of such rooms is determined substantially wholly by the sum of the lengths of the beds. Each wall 12 is recessed at 28 to receive a mirror 29 and is further recessed above the mirror to provide a luggage space 32 which merges into the ceiling 13. The bottom of the bed is curved to merge into the side and aisle wall in the vertical position and a curtain 41 attached to the end of the bed and to a roller blind 42 on the transverse wall 12 prevents articles falling off the end of the bed on to the floor. The aisle walls are double walled and on one side of the door 49 contain toilet articles such as medicine chest 67, wash-basin 65, &c. which in the normal position would obstruct the movement of the bed, but for the provision of levers which are struck by the bed to turn the basin out of the path of the bed and a hopper lid 63 is closed in a similar manner. On the other side of the door 49 is a recess in the aisle wall into which the door slides and in front of this recess is a wardrobe cupboard 51 which is open at the bottom 54<SP>1</SP> and a further recess 56 with a shelf or table 57 for night use. A motor 39, Fig. 2 (not shown), with reduction gear is attached to the end of the bed and to the wall by crank and link and is adapted to lower the bed against the resistance of a counterbalance spring if necessary. When the bed is in the upright position the motor is obscured by the back 46 of a folding chair hinged to an offset portion 23 of the side wall 12 which houses a heater 27, the chair being adapted to collapse as the bed descends. Ventilation is provided by an inlet duct 14 and an outlet 84 under the door 49. Panels in the aisle provide access to the pipes of the wash basin &c. and a boot cupboard in the room is provided with a door in the aisle for the removal of boots.

Title: High-pressure sodium vapor lamp
Inventor: HANNEMAN RODNEY ELTON
IPC: H01J61/22
Filed: 1968-02-13
Abstract: 1,211,175. Metal-vapour lamps. GENERAL ELECTRIC CO. 13 Feb., 1968 [16 Feb., 1967], No. 7099/68. Heading H1D. Sodium cleanup in a high-pressure lamp having an alumina envelope with a filling containing a sodium-mercury amalgam and an inert gas, which sodium exerts a partial pressure of 10 to 1000 torr. in operation, is prevented by arranging that the vapour pressure of sodium is lower than the equilibrium vapour pressure of sodium over sodium aluminate tending to condense at the coolest alumina surface in said envelope so that said tendency is inhibited. The required conditions may be obtained by adjusting the quantity of amalgam and the atomic fraction of sodium therein, having regard to the temperature of the coolest alumina surface in operation. The quantity of amalgam may exceed that vaporized in operation so that the sodium vapour pressure is excess-limited. Under this condition with the coolest alumina surface at a temperature of 600 to 1000 C., the atom fraction of sodium in the excess amalgam is from 0À6 to 0À8. The partial vapour pressure of the mercury is less than 10 atmospheres. Alternatively the amalgam may be totally vaporized so that the sodium vapour pressure is amount-limited. In the lamp shown, niobium end caps 12, 12<SP>1</SP> sealed to the alumina envelope 11 support tungsten electrodes 14, 14<SP>1</SP>, a niobium dummy exhaust tube 16<SP>1</SP> and a niobium exhaust tube 16 which is pierced at 18 and may form a reservoir where excess amalgam collects. The envelope 11 is supported by a single side rod frame 21 in an outer vitreous envelope 2 which is evacuated and provided with getter channels 25 containing barium powder. The inert gas is xenon. An oxygen-absorbing metal such as yttrium may be provided in the lamp as described in Specification 1,211,176 to destabilize sodium aluminate.
